It's no secret that the culinary industry is cutthroat: Studies have found, for example, that 60 to 90 percent of new restaurants fail within the first three years. Other areas of the food space are no less difficult to navigate.

A select few in that world, though, have managed to surmount the odds, with some even developing business ventures outside their original niche. Chefs step out of the  kitchen to double as writers and TV hosts; restaurant owners become brand ambassadors. It's not surprising, then, that several of AdWeek's recently crowned "30 Most Influential People In Food" have a flair for entrepreneurship.

Here are six food innovators who have cooked the competition to become some of the most prominent leaders in their field.

1. Mario Batali

Mario Batali might have one of the best-known names in the food industry. The author of 10 cookbooks (and counting), the two-time James Beard Award winner has taken his talent from the kitchen to the boardroom, presiding over a veritable empire of eateries--with an impressive success rate. Together with his business partner Joe Bastianich, the celebrity chef co-owns restaurants and Italian marketplaces in New York City, Los Angeles, Las Vegas, Chicago, Singapore, and Hong Kong.

2. David Chang

In 2004, the now-famous chef opened the first restaurant in his Momofuku empire--a noodle bar in New York City's East Village--and despite the obstacles including heavy debt and a flooded dining scene, managed to strike gold. Today, he oversees a wide array of establishments, including 13 restaurants, a bakery, two bars, and a cutting-edge culinary lab, in New York, Sydney, Toronto, and Washington, D.C. And just last month he founded a new startup called Ando, a delivery-only restaurant where customers order using an app and get their food brought to them through UberRush.

3. Tyler Florence

Though best known as host of  the Food Network's The Great Food Truck Race, chef Tyler Florence  also heads two successful California restaurants and has a signature line of cookware, which he launched on Home Shopping Network in 2009. Recently, the two-time James Beard Award nominee founded Sprout, an organic baby food company, and launched  Yumavore, a social media app for home cooks.

4. Ina Garten

Another Food Network celebrity, Ina Garten--known to most as the Barefoot Contessa--doesn't come from a traditional culinary background. Garten took a leap into the industry as an outsider when, in the 1970s, she bought a specialty food store in the Hamptons. After closing the store in 2003 to focus on her TV career, Garten used her Food Network fame to launch a collection of limited-edition baking mixes and sauces in supermarkets, and to author 10 successful cookbooks.

5. Gail Simmons

From page to plate, Gail Simmons knows good food. A judge on Bravo's Top Chef, the Canadian food writer--author of Talking With My Mouth Full--also serves as special projects director of Food & Wine, where she oversees the magazine's massive food events. In 2013, Simmons became one of Babson College's "entrepreneurs in residence," mentoring student entrepreneurs and working with the college's Center For Women's Entrepreneurial Leadership.
